Asynchronous SpaceWarp (ASW) enables users to run the Oculus Rift on lower specification hardware than our current recommended specification.
ASW applies animation detection, camera translation, and head translation to previous frames in order to predict the next frame. As a result, motion is smoothed and applications can run on lower performance hardware.
The Rift operates at 90Hz. When an application fails to submit frames at 90Hz, the Rift runtime drops the application down to 45Hz with ASW providing each intermediate frame.
By default, ASW is enabled for all supported Rifts.
ASW tends to predict linear motion better than non-linear motion. If your application is dropping frames, you can either adjust the resolution or simply allow ASW to take over.
ASW requires the following:
Until the minimum specification is released, we recommend the following GPUs for ASW testing:
|Manufacturer||Series||Minimum RAM||Minimum Model|
To enable ASW testing:
While testing your application with ASW, you can switch between rendering modes:
